Downgrade firmware at ue50tu7100uxru

Hi, is it possible to downgrade firmware at ue50tu7100uxru.
Built-in browser doesn’t work with our local Grafana after last upgrade. Topic at the Grafana forum.
Maybe there is possible to install other browser?

If you are a developer you should ask this on the Samsung Smart TV Seller Portal.

If you are an end user then you can try for your region and support for Smart TV there.

Hope this helps,
